What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a car parked on a hill has potential energy because of its height.

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy is E = mass x gravity x height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

At which point on a roller coaster is the kinetic energy at its maximum?

Back

The kinetic energy is at its maximum at point C, where the roller coaster is moving the fastest.

Front

At which point on a roller coaster is the gravitational potential energy at its maximum?

Back

The gravitational potential energy is at its maximum at point A, where the roller coaster is at its highest point.

Front

What is thermal energy?

Back

Thermal energy, also known as heat energy, is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is the relationship between potential energy and height?

Back

The higher an object is, the more potential energy it has. This is because potential energy depends on the height of the object above the ground.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, as it converts potential energy into kinetic energy.

Front

What is an example of kinetic energy?

Back

An example of kinetic energy is a bowling ball rolling down a lane, as it is in motion.

Front

What type of energy is involved in photosynthesis?

Back

Photosynthesis involves light energy, which plants convert into chemical energy.
